Intimidate states
You can use Intimidate to force an opponent to act friendly toward you for 1d6 × 10 minutes with a successful check. The DC of this check is equal to 10 + the target’s Hit Dice + the target’s Wisdom modifier.
Success: If successful, the opponent will:
- …give you information you desire
- …take actions that do not endanger it
- …offer other limited assistance
After the intimidate expires, the target treats you as unfriendly and may report you to local authorities.
Fail: If you fail this check by 5 or more, the target attempts to deceive you or otherwise hinder your activities.
Action Using Intimidate to change an opponent’s attitude requires 1 minute of conversation.
Retry? You can attempt to intimidate an opponent again, but each additional check increases the DC by +5. This increase resets after one hour has passed.

Fear effects include spells with the fear descriptor, anything explicitly called out as a fear effect, anything that causes the shaken, frightened, or panicked condition, and all uses of the Intimidate skill. Intimidate, in particular, is a mind-affecting (influencing or controlling their behavior) fear (create, enhance, or manipulate fear) effect
Emphasis added by me to clarify the terms using their definitions in the rules. If it indeed does work on a PC, that would mean a PC would be forced to
